POLYCILLIN vs UNIPEN IN PLASTIC CONTAINER
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Polycillin (ampicillin) is a beta-lactam antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), disrupting peptidoglycan cross-linking, leading to cell lysis.
Inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), inhibiting transpeptidase activity and peptidoglycan cross-linking.
250-500 mg orally every 6 hours or 500 mg intravenously every 4-6 hours for moderate to severe infections.
250-500 mg intravenously or intramuscularly every 4-6 hours. Maximum dose 12 g per day.

Terminal elimination half-life is 0.5-1 hour in adults with normal renal function; prolonged to 7-10 hours in anuria.
0.5-1 hour (normal renal function); prolonged to 2-5 hours in renal impairment
Renal excretion of unchanged drug accounts for 60-80% via glomerular filtration and tubular secretion; 20-40% is hepatically metabolized and eliminated in bile/feces.
Renal: 60-90% unchanged via glomerular filtration and tubular secretion; biliary/fecal: minor, <10%
